一位常年做GPU优化的人对理想能让Orin跑VLA很高评价
理想TOP2· 2025-12-06 15:16
2025年12月5日TOP2在北京与一位常年做GPU优化的群友线下交流,其认为理想能让Orin跑VLA是一 个很有水准的工作。 认同"理想是在教英伟达怎么压榨芯片能力"这句话既偏颇又有事实依据是get到理想这项工作很有水 准的核心锚点。 能够显著优化寄存器复用效率(Register Reuse),有效规避Orin架构上因寄存器压力过大导致的溢出 (Register Spilling)。 理想可能通过显式插入Ampere架构特有的异步拷贝指令(Async Copy),将计算流水线与显存访问 的延迟掩盖(Latency Hiding)做到极致。 敢于投入资源深耕此领域,证明了理想团队具备深入分析SASS(流多处理器汇编)并在指令级挖掘 硬件潜能的核心能力。这是一项高门槛的系统工程。 2025年8月8日,理想詹锟表示:"我们与英伟达进行了深度架构对齐,基于PTX(Parallel Thread Execution)指令集重构了底层算子,并打造了自研推理引擎,成功突破了通用TensorRT算子集的性能 天花板。" 詹锟提及的与英伟达深度交流,实质是指在Orin芯片(Ampere架构)微架构层面获得了原厂级的技 术指引 ...

理想连发两篇VLA机器人论文
理想TOP2· 2025-12-02 07:29
2025年11月24日理想发布Compressor-VLA与AVA-VLA。 Compressor-VLA提出了一种针对机器人操作场景的高效视觉压缩方案,旨在解决端到端模型太重、太慢的落地难题。教会了机器人带着目的去观察,通 过语言指令过滤掉视觉垃圾,用更少的算力实现更精准的操作。 现在的具身智能大模型存在极其严重的算力浪费: 像一个强迫症患者,花费巨量算力去处理背景墙纸、地板纹理等无关紧要的视觉信息,导致推理延迟 过高,无法满足机器人的实时控制需求。 反直觉现象: 为了给模型减肥,传统做法是直接丢弃视觉token。这种盲目剪枝会导致灾难性后果——模型为了降低计算量,可能会保留纹理清晰的桌布 图案,丢弃了模糊但至关重要的物体边缘或把手位置。 现有的压缩算法是任务无关(Task-Agnostic)的。也就是说,压缩器是个瞎子,它只看图片本身,根本不知道机器人当下的任务是拿苹果还是关抽屉。这导 致在压缩过程中,关键的任务线索被当做噪声误删了 。 AVA-VLA针对现有端到端机器人大模型最核心的健忘问题,提出了一套工程化解决方案。 以下为更细化论述: 解决方案框架 采用了一种双通道互补结构,类似于指挥官 + 工匠的 ...
